A little BASH question (I think)

Hey there.
I'm working on some pacman script, and for that I use the following command:
`echo n | pacman -Suy >text.out`

text.out includes the data I want to have in the file. but pacman still spitts some output to the screen, which I'd like to hide.

Can you please tell me how to do so?

Thanks in advance.

Re: A little BASH question (I think)

There are 2 out streams that are usually put on console:
stdout (standard output, number 1 = default)
stderr (standard error, number 2)

You can redirect them like this:
>stdout.txt 2>stderr.txt

or both to same file like this:
&>both.txt

Re: A little BASH question (I think)

If you want to redirect all output, then you need to handle stderr streams too.
redirecting output streams

EDIT: Aww. slow on the trigger. Oh well, teach a man to fish..

Sorry, I've been bored... when the mods (*ahem*) get around to cleaning up the off topic posts, my count is gonna plummet again.
